摘要：

With scanning tunneling microscopy in air a large corrugation was observed for the PbS(001) surface when using a small positive tip bias voltage. The observed periodicity of this corrugation does not correspond to the crystallographic periodicity, but rather to the periodicity of the wave function at a maximum of the valence band. This effect can be explained in terms of a charge density wave distortion at the surface of the crystal.
